Solaris 10 64 bit counters in SNMP?

Are the interface extensions that support 64 bit counters available anywhere in Solaris 10 03/05? I've been looking for things like the ifXTable and more specifically ifHCInOctets etc... but can't find them on the machine. I've tried some web searches and even sun site searches but can't seem to even find any discussion about them.
